You're much better off with a dehumidifier. The heated clothes airer will accelerate moisture getting into the air and increase the problems that brings. A dehumidifier will dry the washing without any of those problems and probably for about the same cost per load.
I have a Lakeland and dry the clothes flat across the rails. Time consuming as turn clothes over but worth it. Put a sheet or towel over it that needs drying and keeps heat in. Also heats the room as others said.
About 1/3 of a unit an hour for my lakeland one (300w ish can't remember the exact figure). Check you tariff for your unit price and divide by 3 for a rough idea.
I did, but obviously it only heats the rails and not very warm - the laundry took forever to dry. So, I experimented and now on a normal rail I hang the clothes on hangers as if someone were wearing the clothes and they dry overnight for free!
